Abstract

PURPOSE: To permit smooth supply of slurry and improved the durability of an elastic tube by revolving a pair of rollers around the shaft of rotation and allowing said pair of rollers to roll along the outer surface of an elastic tube at the same time, squeezing the elastic tube from both sides.
CONSTITUTION: A pair of rollers 22 revolves around the shaft 19 of rotation when it rotates, and the rollers roll along the outer surface of an elastic tube 16 at the same time, squeezing the tube 16 from both sides. As a result, the inner peripheral surface of the elastic tube 16 is prevented from being pressed and elongated, and wear-out of the tube 16 can be prevented, to have its durability improved. Further, the section of tube 16 can be recovered to an elliptical form spontaneously after passing through the rollers 22, so slurry can be sucked efficiently into the tube 16. Therefore, need of a pump case 14 can be eliminated theoretically, requiring only installation of a cover, and thus the pump can be manufactured at a low cost.
